摘要:
A decurl apparatus includes a heating device to heat an image recording carrier web at a constant temperature, which exceeds the glass transition temperature of a support for a constant time period; and a cooling device for subsequent cooling of the image recording carrier web to a temperature equal to or lower than the glass transition temperature, while the image recording carrier web maintains a predetermined shape. The heating device includes an induction-heated heating roller and holding rollers arranged at arbitrary angular positions with respect to the outer circumference of the heating roller. As a result, the image recording carrier web is reliably decurled by a simple construction without being influenced by a transfer velocity or the like.

摘要:
Disclosed are a silver halide emulsion which comprises multi-layered silver halide grains each having a major face of {100}, having a total Cl content of 20 mol %/mol of Ag or more and having an aspect ratio of 2 or more and which has been sensitized by selenium and/or tellurium sensitization, and a silver halide photographic material comprising the emulsion. The emulsion has a high sensitivity and a low fog, while having a high covering power. The intergranular uniformity of the halide composition in the multi-layered silver halide grains in the emulsion is good. Rapid processing of the photographic material is possible.
